A preview of Circuit Diagram 2.0 is now available to download. Please note that it is still in the development stage, and you may encounter problems using it.

Design Your Own Components

A completely redesigned system for components, which will now be loaded at runtime rather than being hard-coded into the application. They will no longer be written in code, but in XML, making it easy for anyone to write their own components to use in their diagrams.

This will enable the following features:

This update fixes an issue when using Circuit Diagram on computers with some non-English languages.

New Components and Features

The following have been added:

• Label (add text your diagrams)
• US-style resistor

Custom Components
You are now able to include a component in a diagram even if Circuit Diagram does not have built-in support for it. By placing the new component titled "Custom Component" (found under the External Connection category in the toolbox), you can choose a PNG image to be displayed in your circuit diagram.

This enables you to export to PNG or print the diagram containing your custom component.

Please be aware of the following when using this feature:

Recent Files
There is now a list of your last 10 documents, which can be found under File->Recent Files to make opening recent documents easier.

New Components
The following components have been added:

This version has been in development for a while now, and it introduces many new features and components. Due to reasons described below, you must manually uninstall previous versions and then install this version - you will not be notified about this update.

User Interface
The new user interface should make designing circuits much easier.

Version 1.0 of Circuit Diagram will be a major update with many new features.

The first of these is the brand new user interface, with a new theme and toolbox. This enables components to be represented by icons rather than the current text representation, making it easier to quickly find the component you need.

This version adds transistors and improved support for MOSFETs, light dependent resistors and toggle switches. It also adds full undo/redo support and confirmation when closing with unsaved changes.

This release adds a voltmeter and ammeter, partial undo and redo functionality, and allows you to choose a resolution when exporting as a PNG image.

This version adds a microcontroller, potentiometer, variable resistor, thermistor and zener diode. You now able to flip certain components e.g. diode, and open files directly from Windows Explorer.

This version enables you to resize components, flip op amp terminals and adds three new components.
